  1. The obvious and widely available option with those lenses would be the SLR Magic Anamorphot-50 1.33x. On the 35mm you could probably also get away with the SLR Magic Compact Anamorphot-40. Beware of the heavy blue flaring. Sharpness gets nice from F4 and up. Vintage (more pricey, rare) options would include LA7200 and Century WS-13. Check out Tito Ferradans' Youtube reviews for all the aforementioned.

    Current high-end option would be the Letus Anamorphx http://www.letus35.com/letus-anamorphx-pro-1-3x-adapter/

    I wonder if JVC  can get their hands on the popular GH5S/E2/BMPCC4K/Terra4K sensor to stick it inside the LS300 mk2? I'm sure that would make many people very happy!

    Yeah and just bring a smaller / hybrid variant as well. The specs of this thing are (still) fantastic...they should be able to put this tech in a smaller package by now. But I guess the hybrid market isn't their focus...

    Talking about G85 & Sigma 18-35 combo:

    What version is prefered? Canon or Nikon mount?

    What adaptor to get? Single adaptor or boosted?  Dumb or Metabones?

    If you want to control the aperture through the camera, you need a smart adapter. I believe on the Nikon adapter there is a manual aperture lever, but you'll have to check as I have the Canon one.

    For choosing between speedbooster or not: determine what you need:

    With speedbooster you get a fullframe equivalent of around 25-50mm f2.5

    Without speedbooster fullframe equivalent of 36-70 F3.6

    Or get both adapters with and without glass to effectively get two zoom ranges from one lens! The Viltrox are quite affordable. Just don't plan on relying on continuous autofocus.

  4. I really liked Caleb's point in the video above: what if Canon had released an APS-c body with 4K, DPAF, fully articulated screen, headphone jack and 4K 10 bit 422 out?
    Somehow sounds better, video folks might have been less dissappointed than they are now, but it's kinda the (video)camera the R is atm...

    (Still no way I am going to get it though haha... )

    Thanks for the video, I have the 70-200 as well, just fantastic, but not a run and gun lens. 

    For your consideration, the Sigma 50-150mm F2.8... The version without image stabilization is a very nice compact lens. Designed for aps-c. Can sometimes still be found new, although it has been discontinued... I hope Sigma comes up with a similar specced lens, as the new 50-100 F1.8 is so massive.

    The differences between the two images are significant.  I can tell them apart,

    Claiming to be able to tell them apart, with the actual lens and camera data provided is bit easy, no?

    Everybody agrees there can be subtle differences between different lenses, like in the example of Andrew, and also the one you provided (noting that adding an APO filter is quite the change to a lens!).

    Let's keep it simple and general: using equivalence math, you can pretty precisely predict and match the results of certain lenses on certain sesnsor-sized camera's. That's the essence. For evidence: see @BTM_Pix above (and countless others).

    I feel this point gets unnecessarily muddied when focusing on all kinds of specific details of rendering of a specific lens.

    Hopefully this is the last thread about it but lets say it one more time: Perspective only depends on the distance from the lens. You can then adjust the focal length/aperture for a given sensor size to get a specific FoV and DoF. 

    Cheers Don. Understanding equivalence was a super useful, practical insight for me. So if a thread keeps a constructive and inquisitive tone, I am glad to see people explaining and listening to each other :blush:

  8. @Pedro Please do the test. This is not about opinions.

    The pictures you share illustrate the behaviour of different focal lengths on a given sensor size.

    The whole point is the effect of different sensor sizes trying to frame exactly the same scene from the same distance. You can shoot the exact same picture on those different sensor-sized camera's by using equivalent lenses (see my previous post for example).

    This also goes for your GH2 and a6500. Tell us what lenses you own and we can help you try it out.

    What about lens distortion and lens compression??
    -> shooting portraits with 50mm in a FF is not the same as a  25mm in a m4/3... 

    It can be the same. Put your m4/3 camera with a 25mm f1.4 next to a FF cam with a 50mm at F2.8. The framing and DOF will be identical. See the many examples above for more info.

    As a side note: I would like to cheer everyone participating in this nerdy thread on equivalence for not getting into petty arguments (i.e. the way this subject normally ends up being debated haha).

    I wish you'd start a Youtube show Andrew to combat all the misinformation (esp from Northrup) out there

    Kidding? This is exactly the point Northrup has been making all along (i.e. apply crop factor to both focal length and aperture to understand how lenses behave on a specific sensor size). Happy everyone is one the same page now :blush:

    Now let's see whether we ever get an EOS-M speedbooster... The M5 / M50 are not that hot for video, but boosting 'em up to fullframe in such a small package...should be very nice indeed.
